(2x+4) + (3x-9) simplify​

Answer: It's 129°

Step-by-step explanation: Because we know x and 51 are supplementary angles (add up to 180), We can do x + 51 = 180, to figure out that x is equal to 129°.

Hope this helps :)

Step-by-step explanation:

Consider two points on a curve, (xᵢ, yᵢ) and (xᵢ₊₁, yᵢ₊₁).  The distance between them can be found with distance formula:

d = √((xᵢ₊₁ − xᵢ)² + (yᵢ₊₁ − yᵢ)²)

d = √((Δx)² + (Δy)²)

Factor out Δx:

d = √(1 + (Δy/Δx)²) Δx

Adding up the distances from i=1 to i=n, the total arc length can be approximated as:

s ≈ ∑ᵢ₌₁ⁿ √(1 + (Δy/Δx)²) Δx

Taking the limit as n approaches infinity, we get the exact value of s:

s = lim(n→∞) ∑ᵢ₌₁ⁿ √(1 + (Δy/Δx)²) Δx

Which can be written as a definite integral:

s = ∫ₐᵇ √(1 + (dy/dx)²) dx

Answer:

175°F

Step-by-step explanation:

The difference between -82 and 0 is 82.

The difference between 0 and 93 is 93.

Add these two numbers together to find the total difference:

82 + 93

= 175

So, the difference is 175°F

Answer:

x = 15

Step-by-step explanation:

The definition of alternate interior angles means that both of these labeled angles will be equal. Therefore, 60 = (3x + 15)

60 = 3x + 15

Divide this by 3 on both sides

20 = x + 5

Subtract 5 from both sides

15 = x or x = 15

Answer:

The  probability is  Right- tailed

The mean overtime hours for the sample will be at least 9.3 hours is

    [tex]P(X \ge 9.3 ) = 0.3333[/tex]

Step-by-step explanation:

From the question we are told that

    The mean is  [tex]\mu = 9.2 \ hours[/tex]

    The  standard deviation is  [tex]\sigma = 1.6 \ hours[/tex]

    The sample size is n  =  49

      The sample  mean is  [tex]\= x = 9.3[/tex]

Generally the standard error of the mean is mathematically represented as

      [tex]\sigma_{\= x} = \frac{\sigma }{\sqrt{n} }[/tex]

=>   [tex]\sigma_{\= x} = \frac{1.6 }{\sqrt{49} }[/tex]

=>    [tex]\sigma_{\= x} = 0.22857[/tex]

This is a right -tailed probability because the sample mean is greater than the        population mean

 Generally  the probability that the mean overtime hours for the sample will be at least 9.3 hours is mathematically represented as  

           [tex]P(X \ge 9.3 ) =1 - P(X < 9.3 )[/tex]

So

           [tex]P(X < 9.3 ) = P( \frac{ X - \mu }{ \sigma_{\= x }} < \frac{ 9.3 - 9.2 }{ 0.22857} )[/tex]

Here   [tex]\frac{X - \mu }{\sigma _{\= x}} = Z[/tex]

           [tex]P(X < 9.3 ) = P( Z < 0.43750)[/tex]

From the z-table  

            [tex]P(X < 9.3 ) = P( Z < 0.43750) = 0.667[/tex]

So

   [tex]P(X \ge 9.3 ) =1 - 0.667[/tex]

   [tex]P(X \ge 9.3 ) = 0.3333[/tex]

They are asking for a ratio based on how many chaperones per student (in this case 15 students) In other words 15 students for every 2 chaperones.

Answer:

D

Step-by-step explanation:

You can rewrite the equation into slope intercept form and you get Y=10-5x/2 (The whole problem is being divided by 2).

You can leave -5/2 as it is because it's a lot easier to plot the point using Rise over Run or Rise/Run.

Answer:

2/3

Step-by-step explanation:

Simplify the following:

3/4 - 1/12

Put 3/4 - 1/12 over the common denominator 12. 3/4 - 1/12 = (3×3)/12 - 1/12:

(3×3)/12 - 1/12

3×3 = 9:

9/12 - 1/12

9/12 - 1/12 = (9 - 1)/12:

(9 - 1)/12

9 - 1 = 8:

8/12

The gcd of 8 and 12 is 4, so 8/12 = (4×2)/(4×3) = 4/4×2/3 = 2/3:

Answer:

$393.20

Step-by-step explanation:

There are two easy ways to solve this:

1) Use a setup and cross multiply.

First, set up your problem.

$ x    =  40%

$983    100%

$983 is the total amount, so it is equal to 100%. We're trying to find 40% of it, so we can label the amount as $x. Remember, each side has to be in the same type of measurements (i.e. dollars, percentages, inches, etc.).

Then, cross multiply. You should end up with:

100x = 39,320

Then, simplify.

x = 393.2

x = $393.20

2) Convert the percentage to a decimal and multiply.

First, convert the percentage you're looking for into a decimal:

40% × 100 = 0.4

Then, multiply the decimal with the total sales amount:

$983 × 0.4 = 393.2

                   = $393.20

40% × 100 = 0.4

$983 × 0.4 = $393.20

Answer:

$424552300

Step-by-step explanation:

Answer:

25%

Step-by-step explanation:

[tex]percentage \: increase \\= \frac{10 - 8}{8} \times 100 \\ \\ = \frac{2}{8} \times 100 \\ \\ = \frac{1}{4} \times 100 \\ \\ = 25 \%[/tex]

The increase in height from 8 to 10 feet is 25%. To calculate a percentage, divide the value by the total value and multiply the result by 100.

Therefore,

percentage increase

= (10 - 8) / 8 × 100

= 2/8 × 100

= 1/4 × 100

= 25%

Hence, The increase in height from 8 to 10 feet is 25%.
